alfalfa - Purely functional video codec, used for ExCamera and Salsify

  •    C++

Alfalfa is a VP8 encoder and decoder, implemented in explicit state-passing style and developed by the Systems and Networking Research group at Stanford University. It is the basis for the ExCamera and Salsify systems. Almost all the source files are licensed under the BSD 2-clause license. Alfalfa links against x264 to compute the SSIM (quality) of frames. Because this library is distributed under the GNU GPL 2+, so is Alfalfa's ssim.cc file, and the overall Alfalfa package.

gojay - fastest JSON encoder/decoder with powerful stream API for Golang

  •    Go

GoJay is a performant JSON encoder/decoder for Golang (currently the most performant, see benchmarks). It has a simple API and doesn't use reflection. It relies on small interfaces to decode/encode structures and slices.

djson - Fast Go decoder for dynamic JSON

  •    Go

DJSON is a JSON decoder for Go that is 2~ to 3~ times faster than the standard encoding/json and the existing solutions, when dealing with arbitrary JSON payload. It is a good approach for people who are using json.Unmarshal together with interface{}, don't know what the schema is, and still want good performance with minimal changes.

Media decoder and player for Ogg Vorbis/Opus/Theora and WebM video. Based around libogg, libvorbis, libtheora, libopus, libvpx, and libnestegg compiled to JavaScript with Emscripten.

minimp3 - Minimalistic MP3 decoder single header library

  •    C

Conformance test passed on all vectors (PSNR > 96db). Keyj minimp3 conformance test fails on all vectors (PSNR < 96db), and free format is unsupported. This caused some problems when it was used here, and was the main motivation for this work.
